Effective strategies to protect your business from ransomware attacks include layered security. It’s important to have firewalls, antivirus software, spam filters, and local offline backups. Cyberattacks encrypt data and force a business to pay a ransom, which can lead to long-term disruption. This is why businesses should invest in cybersecurity best practices and develop a recovery plan to mitigate damage.
Strategies to prevent ransomware attacks
Firewalls
Firewalls help in preventing ransomware attacks by blocking malware from entering the network. Attacks typically begin with a malicious link in an email or website and then spread through the network to access critical data. Once hackers enter the system, they can encrypt files and halt operations until a ransom is paid. Ransomware attacks can cripple businesses, hospitals, schools, and other organizations — exposing confidential information to the public and making it impossible to operate until the threat is resolved.
Using a firewall with application layer filtering as ransomware strategies helps to detect malicious activity. These types of firewalls use a rule set to analyze the payload in a packet and recognize whether or not it is an attempted attack. A good firewall will also log and audit activity for regulatory compliance and troubleshooting.
Antivirus Software
Ransomware attacks are more than just a nuisance. They cause companies to lose productivity and can even result in layoffs. Cybercriminals hold data hostage with encryption and demand untraceable online currency in return for unlocking it. While large businesses with valuable information are most at risk, hackers also target individuals and small to medium-sized companies.
It is essential to use strong endpoint protection software that includes antivirus with a firewall and behavior-monitoring features. Also, ensure that employees are trained not to open unsolicited or suspicious-looking email attachments or click on banner ads that may contain malware or phishing scams.
Finally, creating regular and automated data backups is a cost-effective way to prevent or mitigate the impact of a ransomware attack. It would help if you stored these backups offline and off your network to increase their reliability.
Offline Backups
The traditional 3-2-1 backup rule — storing at least three copies of data on two different types of media and one of those offsite — is critical for ransomware protection. But backups alone don’t ease restoration processes or mitigate ransomware extortion tactics.
Local offline backups stored on servers isolated from the impacted network provide critical preventing ransomware attacks. Ensure these backups are airtight so attackers can’t access them and corrupt the original data.
It’s also wise to monitor for massive file changes and quickly identify the source of an attack. This will help minimize downtime and the impact on the business. Ultimately, it’s crucial not to pay the ransom demand, as it encourages cybercriminals to continue their attacks. Instead, contact a cybersecurity provider that offers ransomware mitigation.
Multi-Factor Authentication
Multi-factor authentication is one of the best lines of defense when preventing ransomware attacks from impacting businesses. MFA requires verification that the person logging in is who they say they are.
MFA factors can include something you know (such as a password or PIN), something you have (like a security token or hardware key), and something you are (like fingerprint scans, retinal blood patterns, or voice recognition).
The multiple layers of security ensure that if cybercriminals do manage to steal one factor, they will need another to gain access. This makes it 99% more difficult for them to complete a ransomware attack.
Password Managers
Password managers help people create and store complex passwords difficult for criminals to guess or crack. They can also synchronize passwords across multiple devices, so users don’t have to remember them all or risk losing them if they lose or break their computer.
Many of the best password managers use military-grade encryption, considered unbreakable by industry professionals. They also employ cybersecurity experts called zero-knowledge architecture, so the password manager company never has access to the vault containing your encrypted data.
Other useful features include secure sharing, a strong password generator, and cross-platform support. Some premium password managers even offer a free version that is just as secure. The ones that are designed for business come with standard features like audit logging and reports, dark web monitoring, and account health monitoring.

Spam Filters
If employees don’t know how to identify phishing scams and other suspicious emails, they can easily click on an attachment or link that contains ransomware code. Raise staff awareness by conducting security training events and running phishing tests.
Implement a security policy of least privilege so that only the people who need access to data can use it. This also helps to limit the damage that a ransomware attack can do.
Consider implementing an SIEM solution to help your cybersecurity team detect and respond to threats faster. These solutions analyze log and event data from your business’s security solutions and other applications to offer holistic insights into your cybersecurity environment. This lets you quickly detect an incident and take the necessary steps to mitigate its impact.
Web and Email Content Filtering
The most critical defense against ransomware is to take regular data backups. These should be stored on a separate hard drive to bypass any malware and be restored after an attack. It’s also important to keep a schedule for updating software and devices so that any new threats are recognized and blocked immediately.
Cyber attackers often use phishing emails and fake websites to acquire login credentials for online banking, email accounts, or other online services. These attacks can lead to the malware encrypting your business’s data and blocking access until you pay a ransom.
Strong content filters on your work devices are a great way to prevent these attacks. These filters can block time-wasting websites, protect underage students from pornography and grotesque imagery, improve productivity, boost cybersecurity, and help meet regulatory compliance regulations.
